Specification of Letters Patent.

Patented Dec. 19, 1916.

Application fil ed October as, 1913. semi No. 797,747.

To all whom it may concern:

Be it known that we, GEORGE HOMMEL, EDMUND IQNDLER, and WJLLIAM L.PATTER- son, all of Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements in SupportingDevices; and we do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the accompanyingdrawings, forming a part of this specification, and to thereference-numerals marked thereon.

Our invention relates to supporting devices for various articles, suchas cards, pictures, photographs and other objects, and it has for itsobject to provide an improved appliance that is of simple constructionand can be operated readily to grip an object between a pair ofrelatively movable jaws 0r gripping elements.

A further purpose of our improvement is to provide an arrangement ofparts that is effective for holding different sized objects, the partsbeing compactly housed, affording a neat and comparatively inexpensivedevice that is applicable to different uses.

To these and other ends the invention con" sists in certain improvementsand combina tions of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Fig. 1 is a front elevation of one embodiment of theinvention, as constructed for a projection apparatus; Fig. 2 is asimilar view showing the jaws or gripping means separated to receive anobject; Fig. 3 is a view similar to Fig. 2, with parts brokenaway,showing the actuating devices; Fig. 4 is a view similar to Fig. lwith parts broken away as in Fig. 3; Fig. 5 is a sectional view; Fig. 6is a rear elevation; Fig. 7 is a transverse sectional view on the line77 of Fig. 2, and Fig. 8 is a horizontal sectional view on the line 88of Fig. 2.

Similar reference numerals throughout the several figures indicate thesame parts.

The invention may be carried into effect in a number of different ways,and for the purpose of illustrating one practical form, we have shown anarrangement adapted for holding cards or pictures for employment withprojection apparatus, and in the drawings 1 constitutes a frame orsupport which .members lengthwise of is recessed at 2, to afiordanopening in which the operating parts are housed in a manner that willnow be described.

3 designates a cutaway portion or depres sion in one side wall of theframe, the purpose of which will hereinafter be apparent.

Arranged upon the frame 1 areactuating devices, consisting preferably ofa pair of links 4 and 5 pivoted at 6 and 7, respectively. The links 4and 5 are connected forsimultaneous movement by means of supportingmembers 8 and 9, which are arranged on opposite sides of the pivotal'points of the links. This affords an arrangement whereby the links arealways in parallelism, and the supporting members are also retained inparallelism during their movement from their extreme outer position, asshown in Fig. 3, to their extreme inner position, as shown in Fig. 4,the movements of the supporting members being limited and determined bythe walls of the frame. It will be noted that each of the supportingmembers is, shorter than the recess in the frame, to permit limitedmovement of the supporting the frame. The lengthwise or longitudinalmovement of the supporting members serves to move the jaws or grippingmeans toward and from eachv other in the manner that will shortly bemade clear. The actuating devices are operated by means of a suitablefinger piece 10 fixed on the post 7 which extends through the frame andcarries the link 5.

The gripping means or jaws are preferably s'lidably arranged on thesupporting members, so as to permit'a relative lengthwise movementbetween them and the supporting members. This enables the jaws to extendthe, entire length of the recess 2, and to have the proper movementtoward and from each other, necessary for engaging and disengaging anobject. To this end, .we provide a pair of slides 11 and 12,respectively, one of which preferably overlaps the other, as shown inFig. 7. In a device such as shown in the present embodiment, theoperating parts are preferably constructed of sheet metal which is moreor less yieldable, and affords a close engagement between the respectiveslides, presenting a substantially fiat, smooth supporting surface. Theslides 11 and 12 carry means for holding them in members, such as, forinstance, the plates 13, suitably secured to the slides and providedwith flanges 14: on the rear faces engaging the edges of the supportingmembers. The slides are provided on their front sides with coeperatingflanges 15 which engage the opof the card or picture, although it willbe understood that any engaging element comprising a part of thegripping means would be the equivalent of the flanges that have justbeen described. In the nor- =mal position of the parts, the ends of thejaws or gripping means engage the adjacent walls of theframe. Thisprevents endwise movement of the jaws, so that when the actuating linksare operated to move the supporting members, the jaws will be movedtoward or from each other as the case maybe.

For holding an object such as a card, the gripping jaws are firstseparated, the card being placed between the cooperating engagingflanges, and then the jaws are moved toward each 'other until the objectis engaged b the flanges 15. If for any reason it is desirable to removethe gripping means, from. engagement with the supporting members, thiscan be done by slightly lifting the ends of the jaws adjacent to therecess 3 until the flanges 16 are free to move over the edge of theframe.

We claim as our invention:

1. The combination with a frame, of a plurality of actuating devicespivotally mounted on the frame and arranged in parallelism, supportingmembers connecting the actuating devices, and coeperating grippingmeansdisposed on the supporting members.

'2. The combination with a frame, of an actuating device pivotallymounted on the frame, supporting members connected to the actuatingdevice on opposite sides of its pivot, means for retaining thesupporting members in parallel arrangement, and cooperating grippingmeans disposed on the supporting members.

3. The combination with a frame, of a pair of supporting members,actuating means pi votally arranged on the frame and connected with thesupporting members for effecting movement thereof, means for retainingthe supporting members in parallelism posite edges and from each andcoeperating gripping means disposed on the supporting members.

4. The combination with a frame, of a pair of actuating links pivoted onthe frame, supporting members'connecting the ends of the actuatinglinks, slidable gripping devices carried by the supporting members, andmeans on the frame engaging the gripping devices and preventing endwisemovement thereof.

5. The combination with a frame, of a pair of actuating links pivoted onthe frame, supporting members connectingthe ends of the actuating links,gripping means embody ing" slides arranged-on thesupporting members,each of said slides including flanges on its rear face engaging thesupporting members and a flange on'the front face coeperating with theflange on the other slide to hold acard or'other article therebetween.

6. The combination with-a-plurality of actuating devices arranged inparallelism, of supporting members connecting the actuating devices andadapted to be moved toward other by the actuating devices andcooperating gripping devices mounted on the supporting members.

7. An adjustable card or sheet retainer comprising a plurality ofsupporting members connected by means foreffecting move ment of themtoward and from each other, and overlapping plates arranged upon andpermitting slidable movement 'of the supporting members longitudinallyof the plates and provided with oppositely disposed gripping devicescoeperating to retain said card.

8. An adjustable card or sheet retainer comprising a pair of oppositelyarranged gripping devices engaging edges of the article to be held, ofsupporting members on which the gripping devices are mounted to permitlongitudinal sliding of the supporting members, and means connecting thesupporting members for effecting adjustment thereof toward and from eachother GEORGE HOMMEL.
